CC -!- FUNCTION: Involved in the aerobic and anaerobic degradation of long-
CC chain fatty acids via beta-oxidation cycle. Catalyzes the formation of
CC 3-oxoacyl-CoA from enoyl-CoA via L-3-hydroxyacyl-CoA. It can also use
CC D-3-hydroxyacyl-CoA and cis-3-enoyl-CoA as substrate.
CC {ECO:0000256|HAMAP-Rule:MF_01621}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(3S)-3-hydroxybutanoyl-CoA = (3R)-3-hydroxybutanoyl-CoA;
